The smell of these muffins baking takes me back to chaotic Sunday mornings when my roommate would hover around the oven asking if they were done yet. We started making them because meal prep sounded boring, but pulling twelve golden domes out of the tin felt like a tiny victory every week.

My neighbor started requesting these after she smelled them through our shared wall. Now we swap muffin tins over the balcony when she has extra veggies from her garden and I have eggs to spare.

Ingredients

  • 8 large eggs: Room temperature eggs whisk up fluffier and incorporate more evenly with the mix-ins
  • 1/4 cup milk: Whole milk makes them tender but any milk works perfectly fine
  • 1/2 tsp salt and 1/4 tsp black pepper: Enhances all the other flavors without overwhelming the delicate vegetables
  • 1/2 cup diced bell peppers: Red peppers add sweetness while green ones bring a slight bitter edge that balances richness
  • 1/2 cup chopped spinach: Squeeze out excess moisture after chopping so your muffins do not turn soggy
  • 1/4 cup diced red onion: Adds a mild bite that mellows beautifully in the oven
  • 1/2 cup cherry tomatoes: They burst slightly and create little pockets of juicy sweetness
  • 3/4 cup shredded cheddar cheese: Sharp cheddar stands up to the eggs but any cheese you love will work
  • Optional mix-ins: Fresh herbs make them taste fancy and red pepper flakes add just enough warmth

These saved me during finals week when I needed something homemade but had zero time to cook. My study group started showing up early just to snag the warm ones.

Making Them Your Own

I have learned that almost anything works in these muffins. Leftover roasted vegetables from dinner last night? They are perfect. Extra cheese from taco Tuesday? Throw it in.

Storage Magic

They freeze surprisingly well so I always double the recipe. Wrapping individually before freezing makes reheating so much easier on busy mornings.

Serving Ideas

These work for breakfast lunch or snacks depending what you pair with them. A piece of fruit makes it a complete meal.

  • Serve with hot sauce if you like morning heat
  • Pair with avocado toast for a filling breakfast
  • Crumble over salads for added protein
